Effect of GnRH Agonist vs GnRH Antagonist on Oocyte Morphology in Polycystic Ovary Syndrome Patients During IVF/ICSI

• Status: Recruiting
• Trial end date: 2021-08-01
• Target enrollment: 0
• Participant gender: Female

Summary

Selection of developmentally competent oocytes enhances IVF efficiency. Usually, oocyte quality is determined based on its nuclear maturation and the presence of specific cytoplasmic and extracytoplasmic morphologic features. Gonadotropin-releasing hormone agonists (GnRH Agonists) and gonadotropin-releasing hormone antagonists (GnRH Antagonists) are used during controlled ovarian stimulation (COS) protocols in order to prevent premature luteinizing hormone (LH) surge and premature ovulation. However, GnRH receptors are also expressed in extra-pituitary tissues such as ovary, but it is still unknown whether the type of GnRH analogues used during COS could affect the oocyte morphology in polycystic ovary syndrome (PCOS) patients. The aim of this prospective, non-randomised, open-label, clinical trial is to compare the effects of two pituitary suppression regimens; GnRH Agonist-Long Protocol and GnRH Antagonist-Flexible Protocol on oocyte morphology in PCOS patients during IVF/ICSI.
